* core: vm: improve MPK reverse lookup performanceWei-Ning Huang2019-04-101-61/+69
| | | | | By storing array offset in the original DKGMasterPublicKeyProposed map, we can locate MPK by proposer ID easily.
* core: vm: cache GPK to prevent DoS (#335)Wei-Ning Huang2019-04-091-1/+18
| | | | Cache GPK so one can not slow the chain down with the ProposeCRS method call.
* core: add cache for DKG MPK and complaint (#334)Wei-Ning Huang2019-04-091-20/+21
| | | | | Since deserializing DKG related items are extremely slow (takes about 3 seconds for 100 items), we cache it in the governance interface.
* core: vm: fineFailStopDKG if MPK not registered (#329)Jimmy Hu2019-04-091-12/+28

| | | | A node is now quailified only if it has no pending fine and staked >= minstake.

* consensus: dexcon: disqualify dead node (#280)Wei-Ning Huang2019-04-091-1/+48
| | | | | | | | | | Since a qualified node might fail stopped, we need to remove them from qualified nodes to maintain network integrity. We do this by inspect the previous round to see if there are dead nodes. A dead node is a notary set node that does not propose any block in the previous round. We disqualify them by fining them so their staked value is 1 wei below minStake. This make them unqualified for being notary set in the follow on rounds.

* core: vm: remove delegation mechanism (#245)Wei-Ning Huang2019-04-091-415/+158
| | | | | | | | | | | | | The current delegation mechanism are prone to unstaking attack. i.e. a malicious attacker could unstake a small amount from a lot of node it staked before and make them unqualified, which leads to potential failure of the network. Since DEXON does not use consensus like DPoS, node is required to have at least MinStake in order to become a node. Voting mechanism is not required in our system since qualified node does not depends on the number of votes. Instead of managing the delegation mechanism in governance contract, we should let the owner manage the delegation and reward distribution mechanism on their own.

* core: vm: validate addDKGMasterPublicKey caller properly (#220)Wei-Ning Huang2019-04-091-37/+36
| | | | | | There are two keys in the system: one is the owner's key which is used for stake / unstake. The other is the node key which is used for DKG related operations. We need to allow them to be different so fund renmains safe even if the the node key is lost.
